Nandina plant named ‘NanSid3’

ABSTRACT

A new cultivar of Nandina domestica named ‘NanSid3’, characterized by its foliage with new growth that is reddish in color, its compact, upright mounding plant habit with dense foliage, and its fall color that is red in color.

Botanical classification: Nandina domestica.

Variety denomination: ‘NanSid3’.

CROSS REFERENCE TO A RELATED APPLICATION

This application is co-pending with a U.S. Plant Patent Application filed for a plant derived from the same breeding program that is entitled Nandina Plant Named ‘NanSid6’ (U.S. Plant patent application Ser. No. 15/530,719).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nandina domestica and will be referred to hereafter by its cultivar name, ‘NanSid3’. ‘NanSid3’ is a new cultivar of heavenly bamboo shrub grown for use as a landscape plant.

The new cultivar was discovered as a branch mutation by the Inventor in 2010 in Mission, British Columbia, Canada. The new cultivar arose as a naturally occurring branch mutation of Nandina domestica ‘Gulfstream’ (U.S. Plant Pat. No. 5,656) that was growing in a container at his nursery.

Asexual reproduction of the new cultivar was first accomplished under the direction of the inventor by tissue culture of meristematic tissue in 2011 in Mission, British Columbia, Canada. Asexual propagation by tissue culture and stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘NanSid3’ as a unique cultivar of Nandina.

-   -   1. ‘NanSid3’ exhibits foliage with new growth that is reddish in         color.     -   2. ‘NanSid3’ exhibits a compact, upright mounding plant habit         with dense foliage.     -   3. ‘NanSid3’ exhibits fall foliage that is red in color.

‘Gulfstream’, the parent plant of ‘NanSid3’, is similar to ‘NanSid3’ in growth rate and plant habit. ‘Gulfstream’ differs from ‘NanSid3’ in having foliage with new growth that is bronzy orange in color. ‘NanSid3’ can be most closely compared to the cultivars ‘NanSid6’ and ‘Little Flick’ (U.S. Plant Pat. No. 26,276). ‘NanSid6’ is similar to ‘NanSid3’ in growth rate and plant habit. ‘NanSid6’ differs from ‘NanSid3’ in having foliage with new growth that is more purple in color and in having more finely dissected foliage. ‘Little Flick’ is similar to ‘NanSid3’ in having red foliage. ‘Little Flick’ differs from ‘NanSid3’ in having a larger plant size in height and width.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of a 2 year-old plant of the new cultivar as grown outdoors in a 1-gallon container in St. Thomas, Ontario, Canada. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
